CHAPTER 3 PHYSIOLOGICAL BASES OF HUMAN BEHAVIOR

The Central Nervous System is the Brain.The brain takes information from senses, processes it, makes decisions and sends commands to the rest of the body.

The three major parts of the brain are hindbrain, midbrain, and forebrain. The hindbrain is located at the skull's rear, which is the lowest portion of the brain. It has three identified structures: the medulla. the pons, and the cerebellum. Medulla is responsible in some sensitive body functions such as breathing, heartbeat, blood pressure and body posture. Pons involved in regukating sleep and cerebellum involved in several intellectual functions ranging from the analysis and coordination of sensory information to problem solving. The Midbrain is located between the hindbrain and forebrain. It relays information between the brain and the eyes and ears. The Forebrain, the largest part of the brain, which has left and right sides that are called hemispheres. The left hemisphere controls the right side of the body and the right hemisphere controls the left side of the body.
